U Bolt Kit (Per Side) - Nissan Navara D40

U Bolt Kit (Per Side) - Nissan Navara D40

This U-bolt kit is located on the rear of the vehicle and is used to clamp the leaf spring pack securely to the rear axle housing. It is a critical component of your vehicle's suspension system.

U-bolts are considered a single-use item, as they are designed to stretch when torqued to specification. They must be replaced whenever you install new leaf springs, add a suspension lift, or if they are removed for any other service. Over time, original U-bolts can also suffer from fatigue, rust, and stretching, which reduces their clamping force and compromises safety.

If you fail to replace old or stretched U-bolts, they can lose their grip on the axle. This can cause the rear differential to rotate or shift, leading to incorrect pinion angle, driveline vibrations, and poor handling. In a worst-case scenario, a fatigued U-bolt can break, allowing the axle to separate from the leaf spring, which can result in a catastrophic loss of vehicle control.
